BACKGROUND Intragraft verapamil is effective in treating no-reflow during saphenous vein graft (SVG) percutaneous coronary intervention (PCI). In this study, we assessed the use of intragraft verapamil given pre-PCI to prevent no-reflow. METHODS Patients undergoing SVG PCI were randomized to receive intragraft 200 g verapamil or no verapamil immediately(More)
BACKGROUND & AIMS In cancer patients, metabolic alterations, reduced immune competence and anti-cancer treatment can increase the risk of infections. A rapid-acting nutritional intervention might reduce this risk and support overall treatment. The present study investigated whether one week of intervention with a specific medical food led to fatty acid(More)
BACKGROUND Tegaserod is a 5-hydroxytryptamine-4 receptor partial agonist. Oral administration causes gastrointestinal effects resulting in increased gastrointestinal motility and attenuation of visceral sensation. AIM : To determine the long-term safety and tolerability of tegaserod in patients suffering from irritable bowel syndrome with constipation as(More)
We conducted a double-blind study comparing two dosage regimens of a prokinetic drug, cisapride (10 mg q.d.s. and 20 mg b.d.), with a low dose of a H2-receptor antagonist (150 mg ranitidine b.d.) in the treatment of 155 patients with reflux oesophagitis as determined by endoscopy. The active treatment took 8 to 12 weeks depending on whether complete healing(More)
BACKGROUND Proton pump inhibitors (PPIs) have proved to be effective in treating reflux oesophagitis. Until now, no study had compared the PPIs omeprazole Multiple Unit Pellet System (MUPS), lansoprazole and pantoprazole in patients with reflux oesophagitis. AIM To compare omeprazole MUPS 20 mg, lansoprazole 30 mg and pantoprazole 40 mg for treatment(More)
The mechanical force of injection at 90 minutes opens 13.4% of occluded arteries, but overall, only 2.4% of all culprit arteries (already open and occluded combined) are opened. Thus, although some arteries are opened by the force of hand injection, the frequency of mechanical opening among all arteries is low, and hand injections appear to alter current(More)
We present performance results and an analysis of an MPI/OpenACC implementation of an electromagnetic solver based on a spectral-element discontinuous Galerkin discretization of the time-dependent Maxwell equations. The OpenACC implementation covers all solution routines, including a highly tuned element-by-element operator evaluation and a GPUDirect(More)
We model the quantum dynamics of two, three, or four quantum dots in proximity to a plasmonic system such as a metal nanoparticle or an array of metal nanoparticles. For all systems, an initial state with only one quantum dot in its excited state evolves spontaneously into a state with entanglement between all pairs of QDs. The entanglement arises from the(More)
We present a hybrid GPU implementation and performance analysis of Nekbone, which represents one of the core kernels of the incompressible Navier–Stokes solver Nek5000. The implementation is based on OpenACC and CUDA Fortran for local parallelization of the compute-intensive matrix–matrix multiplication part, which significantly minimizes the modification(More)
OBJECTIVE We investigated two promising 1-wk RBC-triple therapies in comparison to the already well investigated 2-wk RBC dual therapy. METHODS We conducted two randomized, open, parallel group studies in 13 hospitals in the Netherlands. H. pylori-positive patients without active ulceration were randomized to 14-day RBC 400 mg b.i.d. plus clarithromycin(More)
